In 12 cases with uremia, the electrical activity and form and amplitude of Bcg (displacement) were investigated before and after hemodialysis. The uremia was secondary to chronic glomerulonephritis (9 cases), familial nephritis (1 case), polycystic kidney disease (1 case) and chronic pyelonephritis (1 case). During the study digitalis was not given to the patients. The ECG and Bcg abnormalities were irreversible in most cases. In 9 cases the VCG showed hypertrophy of the left ventricle. Considering these facts it is assumed that myocardial hypertrophy might play an important part in the development of irreversible pathological repolarization and hemodynamic troubles in chronic uremia.

The renal vascular response to graded doses of acetylcholine, dopamine and phentolamine, assessed by xenon washout and selective arteriography was used to define the relative contribution of fixed and reversible vascular abnormalities to increased renal vascular resistance in patients with essential or secondary hypertension. The increase in blood flow induced by acetylcholine and dopamine was blunted strikingly in patients with advanced nephrosclerosis, chronic pyelonephritis and polycystic kidney disease and was normal in the kidney contralateral to a significant renal artery stenosis. Conversely, the response to both was potentiated in 9 of 13 (69%) patients with mild essential hypertension. Equivalent potentiation of the response to acetylcholine was induced in normal subjects by increasing renal vascular tone pharmacologically with angiotensin. Phentolamine infused into the renal artery also increased renal blood flow significantly in 6 of 9 (67%) patients with mild essential hypertension, but in none of 15 normal subjects, over a dose reange that paralleled that for alpha-adrenergic blockade. Changes in the selective renal arteriogram were in excellent accord: potentiated response to acetylcholine, phentolamine or dopamine was associated with reversal of the small vessel abnormalities visualized in the arteriogram. The reduced blood flow response in advanced nephrosclerosis or parenchymal disease was associated with a reduced angiographic change during dilator infusion. The results suggest a quantitatively important, functional renal vascular abnormality--perhaps mediated by the sympathetic nervous system--in many patients with mild essential hypertension. Conversely the renal vascular abnormality associated with advanced nephrosclerosis or renal parenchymal disease is largely fixed and is probably due to organic changes.

Substances having the chromatographic behaviour and the bioassay properties of prostaglandins (PGE and PGF) were detected in the urine of 30 patients with kidney disease and 15 healthy subjects. The mean urinary PGE and PGF values in 15 patients with chronic glomerular disease or nephrosclerosis were significantly lower than those of 15 patients with chronic pyelonephritis and other forms of chronic interstitial nephritis, polycystic kidney disease, obstructive nephropathy or diuretic phase of acute renal failure, and of the mean PGE and PGF values found in the healthy subjects. It was suggested that in contrast to disease affecting primarily the renal medulla, chronic glomerular disease and nephrosclerosis are accompanied by a decrease of renal prostaglandin synthesis and/or release.

Seventeen adult patients with end stage polycystic kidney disease underwent renal transplantation. Two groups were identified: (1) those transplanted with retained polycystic kidneys, (2) those prepared with preliminary bilateral nephrectomy. Although there was a shockingly higher incidence in the mortality rate in the non-nephrectomized group, no specific cause could be identified. The results do indicate, however, that bilateral nephrectomy is essential in all patients with a history of pyelonephritis or gross hematuria. Substantial benefit from retained kidneys was noted only during the initial period of hemodialysis.

The native kidneys in patients on dialysis or after transplantation tend to be overlooked until problems occur in relation to them. Their appearance can be variable and does not bear any consistent relationship to the cause of the renal failure; although in some cases, such as polycystic kidney disease, there are specific changes to be seen. Size can also be variable with little correlation to pathology in most cases. Acquired cystic disease of the kidneys is seen in up to 92% of long-term dialysis patients and also can be seen in patients with chronic renal failure. Proliferative changes occur in the kidneys which result in the development of cysts, adenomas and, in approximately 1% to 2% of dialysis patients, malignant lesions. It is probable that these changes are caused by a combination of factors, including circulating agents which are not cleared adequately by dialysis. There is some evidence that these changes are halted, or even reversed following a successful transplant. Problems with infection and hemorrhage may occur in patients with polycystic kidney disease. Problems with infection may also occur in patients with calculi, with longstanding pyelonephritis, or reflux.

The term "renal osteodystrophy" is used to include skeletal disorders of patients with chronic renal failure: osteitis fibrosa, osteomalacia, osteosclerosis, osteoporosis and the frequently associated extraskeletal calcifications. It is the chronic glomerular disease with phosphate retention and resultant hyperphosphatemia on one hand and deficient 1,25 (OH)2 D3 and resultant hypocalcemia on the other to induce secondary hyperparathyroidism. The three most common causes of chronic renal failure in our patients are chronic glomerulonephritis, diabetic nephropathy, hypertensive nephropathy in decreasing frequency, polycystic renal disease occurs in five patients. Other miscellaneous causes include nephrotic syndrome, chronic pyelonephritis, systemic lupus erythematosus, periarteritis nodosa, interstitial nephritis and renal stones. The bone changes are similar in primary and secondary hyperparathyroidism and the incidence of brown tumor is about 3% in the former and 1.5 to 1.7% in the latter. We present one among the 94 dialyzed patients who has long-standing severe chronic renal failure from polycystic kidney disease and develops brown tumor in the mid ulna after 7 years on maintenance hemodialysis. The incidence of brown tumor in our series is about 1.1%. Because of increased longevity of the dialyzed patients, brown tumor from secondary hyperparathyroidism is now more commonly observed. Hyperphosphatemia with serum calcium-phosphate products exceeding plasma solubility of 60 to 75 mg/dl may induce soft tissue and vascular calcification. This explains the much higher incidence of soft tissue calcification in secondary than primary hyperparathyroidism; two of our patients with generalized Monckeberg's type arterial calcification and multiple periarticular calcifications in five patients have been observed.(ABSTRACT TRUNCATED AT 250 WORDS)

Two cases of Dominant Polycystic Kidney Disease (DPKD) are reported in newborns of two different affected families. One of two infants was prenatally diagnosed by ultrasound, few cases of in utero diagnosis being previously reported. The two infants had different course: one had no symptoms (14 months now), on the contrary the other one had abdominal mass at birth and oliguria in the first 48 hours, then acute pyelonephritis at 15 months. The increasing incidence of DPKD diagnosed in infants and children by US screening in risk subjects is stressed and importance of precocious diagnosis for genetic counselling emphasized.

Histomorphometry was performed on transiliac bone biopsies, double-labeled with tetracycline, from 60 consecutively admitted patients (20 women) at various stages of chronic renal failure (CRF). Eleven patients (1 woman) had normal bone resorption and formation indices. Bone resorption and osteoid formation increased with progression of renal failure, but abnormal values were seen even at slightly elevated creatinine levels. Mineralization lag time increased with CRF duration; prolonged values were only seen in patients with polycystic kidney disease or chronic pyelonephritis with advanced CRF. All patients with impaired mineralization also had increased bone resorption. Diabetes mellitus did not protect against skeletal lesions. The biochemical tests were too insensitive to predict type or severity of bone disease, and hand X-rays had no diagnostic value in early stages of renal osteodystrophy.

Glomerulonephritis, pyelonephritis, diabetic nephropathy, and polycystic kidney disease were the four most frequent original renal diseases leading to altogether 500 kidney transplantations in Rostock from 1976 to 1989. A total of 457 pathomorphological specimen (255 transplant biopsies, 159 explants, 43 postmortem grafts) of 348 renal transplants was histologically studied. The most striking findings were a more frequent hyperacute rejection and an earlier loss of explants as well as a higher incidence of relevant vascular rejection in graft biopsies of glomerulonephritis versus pyelonephritis patients. The obtained results suggest a possible disposition of recipients with glomerulonephritis to a more rapid and intense graft rejection in comparison to transplant patients with pyelonephritis as underlying renal disease.

Nine fatal cases of systemic mucormycosis observed in association with renal failure are described. Four patients were hospitalized for chronic renal failure as a consequence of chronic glomerulonephritis, myeloma kidney, chronic pyelonephritis, and polycystic kidney disease, respectively; and five patients presented with acute renal failure. The underlying causes in three of these five patients were gentamycin nephrotoxicity, acute gastroenteritis, and allograft rejection, respectively, and in the remaining two, acute renal failure was the result of extensive renal vascular and parenchymal invasion by mucor hyphae. Tissue invasion with mucormycosis was documented during life in two patients and at autopsy in seven patients. The infection was disseminated in five patients, and isolated pulmonary and rhinocerebral involvement occurred in two patients each. Our observations have shown that patients with renal failure are prone to develop mucormycosis, which carries a grave prognosis if therapy is not instituted in time.
